💡 What is a common use case for a ceramic ball bearing in precision machinery?

These ceramic balls deliver low friction and high wear resistance, handy in high-speed, tight-toleranced systems. - Low friction and wear resistance extends life in high-speed spindles and linear guides
- High hardness reduces deformation and maintains accuracy under load
- Corrosion resistance helps in harsh environments and reduces maintenance
